China’s Export Curb on Chip

The Pentagon plans to issue a first-time contract to US or Canadian companies by year-end to recover gallium, a mineral used in semiconductors and military radar systems, after China curbed exports this month.

China announced the restrictions on gallium and another mineral, germanium, in a move seen as part of the country’s tit-for-tat trade war on technology with the US and Europe. The two metals are crucial to the semiconductor, telecommunications and renewable energy industries. The curbs prompted US Treasury Secretary Janet Yellen to voice her concern during a recent visit to Beijing.
